Abstract

For the production of facial tissue, an improved multifolder configuration has been developed which allows for automated production of sub-clips of tissue to support secondary copacking operations.

Introduction

In facial tissue converting, a slit tissue web of the appropriate width is continuously unwound from a roll, then folded and laid down onto previously folded tissue webs to form a continuous stack of tissues known as a "sausage," which is subsequently cut into individual "clips." The number of tissues within the clips equals the sheet count within the carton for the product being made.

The machine that converts the slit webs from multiple rolls into the sausage is known as a multifolder.Principles of multifolder design and operation are disclosed in US Pat. No. 3,841,620, "Web Folding Apparatus and Method" issued October 15, 1974 to Lee et al., US Pat. No. 3,401,927, "Longitudinal Web Folding Board" issued September 17, 1968 to Frick et al., and US Pat. No. 5,868,276, "Folded Sheet Material Web and Assembly and Method and Apparatus Therefore" issued February 9, 1999, to Loppnow et al. Multifolders are typically designed to fold and form clips of product from tissue and other base sheets at high rates of operation. A characteristic of the multifolder process is that clips of product are produced at the same rate of operation regardless of the sheet count per clip. Automated cartoning equipment accepts and packages clips of tissue of the various counts at the same high rate of operation.

However, when a secondary copacking operation is utilized it then becomes desirable to improve the efficiency of the overall operation by producing larger count clips of tissue that can be easily divided into smaller counts at the copacking operation.

We propose a method to form multiple sub-clips within a master clip of product. The method addresses the problem of providing visual and tactile indicators for each sub-clip so that the master clip can be easily separated into the smaller sub-clips during the copacking process.

Clip Structure

In one embodiment, a master clip is composed of five sub-clips and each sub-clip contains 45 sheets. However, the ratio of sheets per sub-clip and sub-clips per master clip can be varied to suit the finished product requirements.

This process described here produces a means to easily identify and separate each 45 count sub-clip from the main clip. All sheets within the sub-clip are interfolded to provide pop up dispensing for the consumer. The sheets of tissue separating each sub clip are not interfolded. This provides a positive means to easily separate the sub-clips from the master clip. The configuration of the master and 45 count sub-clips is shown in Figure 1.
